VERY BAD SERVICE

I would like to complain how bad their service is. I phoned on the 14 August numerous times to log a fault with my security system. I was even told to test in while on the phone. it has been 5 days and no one has phoned me back for a technician to make arrangements to see the system. The whole reason we phone in the beginning is that we kept getting "failed to test" sms. Now when I phone back on the 19 August, I was told there was nothing logged on the system. THIS IS OUTRAGEOUS, WE PAY OUR BILL EVERYMONTH ON TIME AND THIS IS THE SERVCE WE GET. Not really impressed at the moment as what will happen if we broken into and Blue doesn't respond as they failed on their side to log a fault properly??
